Abstract (en)
[origin: US2013281577A1] The present invention discloses additive compositions, cementitious compositions, and methods for controlling air in cementitious compositions in which colloidal nano-particles are used for stabilizing a water-dispersible defoamer within a cement-dispersant-containing aqueous additive formulation for modifying hydratable cementitious compositions such as cement or concrete.
